Question

Since updating to Big Sur, my Macbook Pro won't recognize my PreSonus Audiobox USB. Per the PreSonus website, a driver is not required for Mac OS. Despite that, I downloaded and installed the Universal Control from the PreSonus site, and it still doesn't work. I'm out of ideas, and would be grateful for any sage advice the community could offer. Thanks.

Answer 1

I also have this problem

Answer 2

According to the Apple Genius Bar guy, with Big Sur (and also it’s predecessor), Apple no longer supports 32-bit applications. As my Audiobox USB was purchased in 2011, it is likely to be a 32-bit device. I purchased a new Scarlet Solo interface, problem solved.

Answer 3

finally solved this problem... missed a step namely allowing my Mac to let studio one use the microphone in m  privacy settings... this set up video worked a charm ...

Answer 4

I'm having the same problem. Audiobox USB 96 worked fine until I upgraded to Big Sur. Now my Mac doesn't recognize it, except that it shows "number of MIDI inputs has changed to 1" whenever I plug it in. But it doesn't show up in Sounds preferences or in Garageband.

I've tried:

- installing Universal Control

- removing all drivers using the app that comes with Universal Control

- re-installing FireWire driver

- removing FireWire driver

And of course restarting after each step.

My Audiobox is roughly 18 months old.
